all likelihood the type of Arvicola californica came from San Fran- 

 cisqiiito Creek, near Palo Alto, California, and that it was taken on 

 October 26, 1841. Various statements and circumstances are against 

 assuming any other place to have been the type locality. For instance, 

 Peale records that at the place where he spent the day of date just 

 designated there was green grass for the horses. He gives a list of 

 birds noted, and says that he hunted and botanized. Peale was at 

 Sausalito, also, where he went to take the naval boat " Vienciennes, " 

 but there is little chance that he collected anything there. He was at 

 this point but two days prior to departure, and seems to have been too 

 fully occupied in packing to have done any collecting. 



The writer has not seen the original description of Arvicola cali- 

 fornica; but the skin collected by Peale, and which Dr. Coues desig- 

 nated as the type, has attached to it a label bearing the following data : 

 "Monograph of American Muridae. Dr. Elliott Coues, U. S. A. 

 No. 10082 Type of Arvicola 'californica' Gala. V. S. Ex. Ex. T. R. 

 Peale." The parchment label is marked "Arvicola californica Peale. 

 10082." Bailey (1900, p. 35) mentions the fact that the skull now 

 accompanying this skin is either abnormal or else never came from 

 the same animal as did the skin. The skull (no. 4156, U. S. Nat. Mus.) 

 belonged to an immature animal. On the right side below the zygoma 

 it is labeled "A. occidentalis." This name is a synonym of townsenclii. 

 The right lower mandible is labeled "A. californica." In some re- 

 spects, mainly the constriction of incisive, foramina, the skull resembles 

 that of Microtus townsendii, but M^ places it with californicus.
